He's saying that the router announcements don't contain any DNS server information. There's an extension/option that can be enabled with router advertisements to make it send this information, similar in function to how DHCP sends out extra info like the default gateway, DNS server, NTP server, WINS servers, etc. To my knowledge this wasn't around when the Kame guys were working on this stuff. I don't think a lot of time has been spent updating the v6 support applications since then and that's why we don't have this feature. This isn't a big deal in dual-stack networks because the clients just do DNS over v4 with whatever the DHCP server gave. In a pure-v6 world... In hindsight it's an obvious oversight that it wasn't included in the first place. -Bob
